Continuation of application Serial No.

To all whom it may concern Be it known that I, ALBERT Gr. Sorrnana, a citizen of the United States, and a resident of Chicago, in the county of Cool: and State of Illinois, have invented certain new and useful Improvements in Combined Hot- Air and Cold-Air Registers, of which the following is a full, clear, and exact specification.

Stated broadly, my invention has reference to a register having two sections through one of which hot-air is discharged from a conduit leading from the furnace, and through the other section whereof the cold-air is withdrawn from the room to the furnace or heater where it is reheated for circulation. The present application is a continuation of, and the subject-matter hereof is divided out of the co- ')ending plication filed by me on October 1918, Serial Number 259,357 for improvements in register structures.

The subject-matter of this application is especially applicable to the type of heaters known as plpeless furnaces or reheaters, and such furnaces are frequently installed in mercantile establishments, such as stores, banks, etc, where the economy of floor space is necessarily of vital importance. To this end I have designed a novel device, one of the objects whereof is the provision of a register structure that any suitable place and the top thereofutilined as a display counter, or when in use in a bank may be in the form of a countinghouse desk for the convenience of depositors and others. Arrangements are made in the structure to protect the cover or top from the heat of the air arising from the heater and thereby preventing the damaging of the cover. Another object of my invention is the provision of register structure from which the hot-air will be discharged through all the exterior walls and in an upward radial direction. while the cold-air is taken in through another ection of the register and through all the exterior walls thereof so that the two opposite y movii currents of air will not interfere with or retard each other.

(Ether objects of my invention are to provide a combined hot-air and cold-air register that is compact in construction, effective in its operation, economical to manufacture and install, and which when installed in a mercantile establishment will add to rather than detract from the appearance thereof. I prefer to accomplish. the divers objects of my invention in substantially the manner and by the means hereinat'ter fully describedand. as more particularly pointed out in the claims, reference being now made to the accompanying drawings that form a partof this specification and which are in a sense merely diagramniatic for the purposes of convenient illustration. l l l In the drawings;

Figure 1 is a vertical end elevation of a register structure adapted for use instores, banks, etc, as a display counter or as a counting-house desk. a

2, and

This structure issubstantially, rectangular in shape, and the hot-air is adapted to be discharged through all the walls and a large portion of the ends of the upper grille, while the cold-air is drawn in through only and a portion of the ends ofwthe lower grilles, the hot-air passageway being disposed longitudinally through the central portion of the interior from end to end thereof with cold-air passageways on both sides. .l he upper and lower grilles 100 and 101. 1 respectively, are each made of two pieces of reticulated sheet metal similar to the grilles in the other types of myregister, shown in my co-pendingapplications, and are bent substantially U-shapeto conform: with the outline of the lower portion of the structure. T-sl1ape,;and provided with lateral flanges 103 along their vertical edges, are employed to secure the end edges of the grilles to- To do this,

vertical flanges 100* p End plates 102 of inverted tors and 101 are made along the adjacent edges of the grille plates so that the flanges may be drawn together by suitable clainp bolts 10% of any desired form, or in any other manner.

A lower strap or ring 105 of L-section receives the bottom edges of the lower grilles and upper and intermediate straps or rings and to the intermediate strap, by bolts or otherwise to assist in strengthening the grilles and straps,- while end boards 109 corresponding in shape with the end-plates 102 are'secured upon the exterior of said plates to cover the flanges and end edges of the respective upper and lower grilles, as shown in Fig. 1.

Secured to and arising from the upper strap is an extension band 11Q that is perforated for ventilating the sand-chamber, hereinafter described, and the top or cover 112 is adapted to rest upon the top edge'of this band in the manner shown. In the event this type of register is used in a store this top or cover may be employed as a. counter for the displayof merchandise or the like, or in the event the structure is for use in the corridor of. a bank, a removable counting-house desl' 113 is added thereto and supported therefrom by suitable end supports or legs 11% that rest-upon the ends of the top or cover 112.

The top deflector 115 is of a substantially pyramidal shape, inverted and slightly elongated, and is supported upon the upper strap in any suitable manner, preferably, '0 providing the upper edges of its walls with downwardly bent flanges 116 that extend over the top and down the outer surface of said strap. The interior of the register below the horizontal plate of the intermediate strap 107 is divided longitudinally by two parallel vertical walls 117 that extend from end to end of the register and divide the interior space into an inner or central hotairpassage'ovay 118 and two outer parallel cold-air passage-ways 119 upon opposite sides thereof. The central upper portions of these walls 117 areprorided with relatively wide substantially V-shaped recesses 120 in which the lower edges of the cold-air deflec- 121 are positioned. These deflectors are substantially. semi-pyramidal in shape with the vertical wall omitted, and their inclined walls extend upwardly from the recesses 120 in the vertical walls 11, toward and are secure-cl to the intermediate strap 10, by pro riding downturned flanges 122 upon the upper outer edges of the deflector walls that fit over the top and down the outer side of the .trap 10? in substantially the same manner as the deflector 11? is mounted upon its strap 106.

From the above it will be seen I have devised a'structure wherein a combined hotair and cold-air register is provided for use in stores, banks, etc, and in which the hotair from the furnace arises through a central passageway that extends from end to end of the register and said hot-air is discharged through the upper rille extending subs antially ez'itirely around the upper portion 01 the structure. The cold air received through the sides of the lower grille into two passage-ways upon each side of and pa allel with the hot-air passage-way and winch also extends end to end of the register, but owing to their shallowness receive the cold air along the longitudinal sides of the register and only a very small proportion of the ends thereof.

The deflector 115 is, preferably, filled with sand or other heat retaining aterial for the purpose o storing a quantity of heat for use when the are is let down, and in order to keep the sand clean, 1 place a suitably shaped plate a on the top thereof.
